Thanks for all the great feedbacks! I painted the inside flat black to give it a more realistic look to the body. The windows haven't been mask off, will be repainting them, and both of the rear fender flares are finished and have been mounted on the body, its pretty wide, the width of the body is 8 cm wide. I only have to make 1 more fender flare for the front right side of the body.
Today, I have added 2 coats of metallic blue on top of the base coat, and this is how it came out.
